Brief Summary:
Zenker's diverticulum (ZD) is a rare benign condition, due to an acquired sac-like outpouching of the mucosa and submucosa layers originating from the pharyngoesophageal junction. Endoscopic techniques like flexible endoscopic septum division (FESD) or per-oral endoscopic septotomy (POES), represent a minimally invasive alternative to surgery or to rigid endoscopic procedure to treat ZD. The goal of the research will be to evaluate the safety of the procedures and to measure Zenker-symptom severity in all patients treated by endoscopic procedures.

Intervention Details:
  • Procedure: Endoscopic septotomy
    Patients will be placed in left lateral decubitus position, either in conscious sedation or under deep sedation with propofol or endotracheal intubation.The procedure will be performed with a flexible standard endoscope and started with initial endoscopic examination with suction of possible retained material insidethe diverticulum. An incision of the bridge between the ZD and the esophagus will be done (using one endoscopic procedure as POES or FESD or other)

Primary Outcome Measures :
  1. Incidence of Adverse Events [ Time Frame: 24 hours after the procedure ]
    Any complications as bleeding, perforation, others

Secondary Outcome Measures :
  1. symptoms after the procedure [ Time Frame: up to 5 years ]
    The frequency of symptoms such as dysphagia, regurgitation, weight loss
